Granular composition comprising dietary fibers derived from green tea and method for preparing the same

Abstract

A granular composition containing dietary fibers derived from green tea and a method for preparing the same are provided. The granular composition may be prepared into granules, which has a suitable size and a shape to eat, using dietary fiber-containing processed green tea, an oligosaccharide and a sugar alcohol as raw materials. The granular composition may also be useful in solving the problems such as dust scattering, choking, and the like due to the good flowability of the granules, and manufacturing goods because the granular composition is easy to quantify due to the good filling properties.

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims priority to and the benefit of Korean Patent Application No. 2018-0132238, filed Oct. 31, 2018, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND1. Field

[0002] The disclosure relates to a granular composition comprising dietary fibers derived from green tea and a method for preparing the same.2. Discussion of Related Art

[0003] Oligosaccharides and dietary fibers are components rich in foods, for example, vegetables, fruits, algae, and the like, and are high-molecular carbohydrates that are excreted from the human body without being digested by human digestive enzymes. Owing to such characteristics of the dietary fibers, the dietary fibers are recently known to have excellent functions as prebiotics that affect the enterobacteria to inhibit the growth of pathogens and promote the growth of beneficial bacteria. In addition, when one eats a sufficient amount of the dietary fibers, the...

Examples

example 1

[0083]Based on the compositions as listed in the Table 1 below, a granular composition was prepared using the following method.

(a) Preparation of Processed Green Tea

[0084]100 g of green tea leaves was primarily extracted with 1,500 g of 70% spirits at 70° C. for an hour, and then secondarily extracted with 1,500 g of purified water at 90° C. for 3 hours.

[0085]70 g of the green tea residue remaining after the primary and secondary extraction was immersed and extracted in 490 g of an aqueous 0.2 M sodium hydroxide solution at 90° C. for 2 hours to obtain an alkali extract.

[0086]The alkali extract was subjected to solid-liquid separation to remove an alkali extract solution, and the remaining solid alkali extract was then washed with drinking water to remove the residual alkali. 210 g of an aqueous 0.2 M acetic acid solution was added to 30 g of the solid alkali extract to neutralize the solid alkali extract.

[0087]The neutralized extract was subjected to solid-liquid separation to remo...

example 2

[0094]A granular composition was prepared in the same manner as in Example 1, except that erythritol was used as the sugar alcohol instead of the xylitol.

example 3

[0095]A granular composition was prepared in the same manner as in Example 1, except that xylitol and erythritol were used together as the sugar alcohol instead of the xylitol.
